I obviously won't get them retuned now
I think you should get them tuned. Some new skis have an excellent state of tune. Some are poorly tuned. Some skis cup due to the materials curing. At least have them checked for being actually flat on the bottoms. I'd also get the edges sharpened to the angles that best suit your skiing style and snow conditions. I'd suggest 1° base edge bevel and 2° side edge bevel if you are a conservative skidding skier, and maybe 0.75° base and 3° side if you are a carver. Detune the tips & tails? What exactly did they do? The tips and tails should be sharp all the way to the contact point with the snow. The parts of the tips that rise above the contact point should be detuned, but not any part in contact with the snow. Detuning the part of the tips and tails that contact the snow was how we did things on the old straight skis with no bottom edge bevel. Ancient history.
Yes, wax. It doesn't have to be anything fancy. I just melt in some universal wax, re-melt and wipe the excess off with a paper towel, and ski. Works for me. The wax that works for us is melted into the pores of the base. The wax on the surface is immediately skied off, or wiped off, or scraped off, or brushed off.
Moguls...a couple of things are poison in bumps. Skiing with your weight on your heels kills you. Rotating your upper body in the direction of the hill ruins turns. Leaning back toward the hill can not work. So...as you crest over each bump, strongly pull both feet back way behind you--it'll turn out to be just right. You'll start out on your tips and end up centered. Keep your zipper pointed down the hill. Reach down the hill with your pole 2" off the snow so your head and shoulders are downhill from your hips.
Powder...You gott'a have your weight equally balanced on both feet. You gott'a have your weight centered fore & aft and maybe just very slightly on your heels--did I say very,very slightly? You gott'a turn smoothly and at the tempo that your skis down inside the snow want to turn. You turn by putting both skis on edge inside the snow. Visualize an airplane banking through a turn. Think of both skis together banking through a turn in the snow. Your body needs to be facing downhill, and you need to be balanced with your head and shoulders downhill and your hips angled for balance. You don't need speed...that's the usual crutch people suggest. You need balance.
